如何在zend服务器中使用php连接到MySQL数据库

Question

我正在尝试使用 php 连接到 zend 服务器版本 7.2.10 中的 MySQL 版本 8.0.11 数据库，但我无法连接它

Warning: mysqli::__construct(): Unexpected server respose while doing caching_sha2 auth: 109 in C:\Program Files (x86)\Zend\Apache24\htdocs\connectdatabase.php on line 7

Warning: mysqli::__construct(): MySQL server has gone away in C:\Program Files (x86)\Zend\Apache24\htdocs\connectdatabase.php on line 7

Warning: mysqli::__construct(): (HY000/2006): MySQL server has gone away in C:\Program Files (x86)\Zend\Apache24\htdocs\connectdatabase.php on line 7
Connection failed :MySQL server has gone away

当我尝试运行我的代码时收到以下警告。

我已经搜索并尝试了ALTER USER 'username'@'hostname' IDENTIFIED WITH mysql_native_password BY "userpassword" 命令，但它对我不起作用

<?php

$servername = "localhost";
$username = "root";
$password = "hello";

$conn = new mysqli($servername,$username,$password);

if(mysqli_connect_error())
{
    die("Connection failed :" . mysqli_connect_error());
}

echo "CONNECTED SUCCESSFULLY";

?>

尝试使用 caching_sha2_password：

ALTER USER 'username'@'hostname'IDENTIFIED WITH caching_sha2_password BY 'userpassword';
